Symptoms
  • Case fan speed on UTM-1 270 is reported as "low".
Cause
The appliance is not defective.

UTM-1 270 units with serial number 0842B01058 or higher are equipped with a different type of case fan. This fan provides the same cooling properties as the previous case fan.

Hardware monitoring software incorrectly identifies the case fan.
Solution
Replace the /etc/sysconfig/sensors/sensors_data.C file with the modified file that you can download from Hardware Monitoring Software Update. The new file will update the hardware monitoring software to correctly handle the operational range of the new case fan.
